WASTE RECEIVER.

Application filed November 2, 1926. Serial No. 145,868.

My invention relates to waste receivers for use in honing or boring engine cylinders, and its main object is to provide means for catching the waste, both liquid and metal, that is 5 discharged in honing or re-boring cylinders of the engine block of an internal combustion engine.

Another object is to provide means for placing the receiver in the proper position 10 beneath the cylinder so that all the waste matter will be caught and so that the receiver will not interfere with the operation 'of the honing or boring tool. Y

l'eretofore the waste matter discharged in honing or boring the cylinder of 'an in tern-a1 combustion engine has been allowed to flow and drop out the cylinders at the lower end thereof. Thus the crank shaft, bearings and other parts of the engine were covered with kerosene, water, or other liquid and with metal filings or shavings, with the result that cleaning the engine after each operation took as long or longer than the actual honing or boring itself. The present 25 invention is intended to save the time spent in the past in cleaning the engine after its cylinders have been bored, honed or otherwise refinished.

Other objects will be found in details of 3 construction and novel combinations and arrangements of parts, as will fully appear in the course of the following description.

In the accompanying drawings, in the several views of which like parts are similarly designated,

Figure 1 represents a sectional view of a portion of an internal combustion engine, to which my invention has been applied,

Figure 2, a sectional view on the line 22 of Figure 1,

Figure 3, a Sectional elevation of a modification of the means for holding the receiver in position beneath the cylinder; and

Figure 4, a'perspective view of the means included in the invention for placing the re ceiver in proper position.

Referring more specifically to the draw ings, my receiver consists of a cup 5 which may have a channeled washer 6 at its upper edge to make a fluid-tight contact between the cup and an engine block 7. In the illustrated embodiment of my invention the cup 5 is composed of a base member 8 with a channeled washer 9 superposed thereon and an annular wall member 10 inserted in the channels of the two washers 6 and 9.

The base member 8 has a nipple 12 for the outlet offliquid waste matter. A hose 13 connected with this nipple, empties into a container 1 1 which maybe any size and form.

To assist in draining the cup 5, means may be used to create a partial vacuum in the hose thereby causing a forced How of the material received in the cup to the receptacle into which the hose discharges. This will also prevent the nipple 12 and the hose 13 from being obstructed by solid matter. The means provided for this purpose as shown in the drawings consists of a nozzle 15 inserted in the hose 13 in such a manner that the outlet of the nozzle will be pointed in the direction of the flow of the liquid through the hose. This nozzle is connected by means of a hose 16 to any convenient source of air under pressure such as a pump 17 or the air pressure system usually found in garages, etc.

The cup may be held in place against the lower face of the engine block 7 by any suitable means. In the drawings the means shown consists of a brace having two screwthreaded parts 18 and 19 connected by a turnbuckle 20. The lower member 19 of the brace is provided with a saddle 21 which rests on the crank shaft 22 of the engine. The upper member 18 preferably has round d end which fits into a depression on the underside of thecup, as seen in Figure 1.

A very simple and practical modification of the brace for holding the cup in place is illustrated in Figure 3. It consists of telescoping members 23 and 24, one of which has a saddle 21 similar to that on the member 19 of the first described brace. The upper member 23 has a collar 25 held in place on the member 23 by a transverse pin 26 which provides an abutment for a coiled spring which by engagement with the saddle at the lower end of the member 24L tends to extend the brace by relative movement of its members and thereby causes itto hold the receiver 5 in fluid tight contact with the end of the cylinder.

A loc-ator 28 shown in detail in Figure 1 is the means used for placing the cup 5 in proper position beneath the engine block. It consists of two U-shaped spring metal parts 29 and 30, fastened together atsub stantially right angles to each other as at 31 by a bolt or rivet. The distance between the legs 31 of the locator member is such that the device will fit loosely into a cylinder 32 of the engine block. Offsets 33 at the lower ends of the legs engage the surface of the engine block beneath the cylinder and these offsets are spaced apart to loosely fit within the upper washer of the receiver.

In the operation of my invention, the locator 28 is first placed in the cylinder 32 of an internal combustion engine as shown by broken lines in Figure 1. It is then pushed down the cylinder until the offsets 33 are disengaged from the walls of the cylinder and extend beyond the same as Shown by full lines in the same figure. The cup may now be placed in its proper position relative to the bore of the cylinder by moving it along the lower surface of the engine block until it has found its place around the projecting offsets of the locator where it is in true alinement with the cylinder bore. When the cup is thus positioned all waste matter discharged. from the cylinder must necessarily enter the same, it being under stood that the cup is held constantly in fluid tight contact with the surface of the engine block around thecylinder by one or the other of the two braces herein described.

Before the operation of honing or boring the cylinder is commenced, and after the brace has been applied as shown, the locator is removed from the cylinder thereby eliminating the only part of the appliance which could interfere with the operation of the honing or boring tool.

Variations may be made in the construction hereinabove described without departing from the spirit of my invention.

' avin thus described my invention, what I claim and desire tosecure by Letters Patent is 1. The combination of a waste receiver comprising a receptacle adapted to engage an open-ended engine block below the cylinder, and means cooperative with. the cranl shaft for holding the receptacle in engagementwith the block.

2. The combination of a waste receiver comprising a receptacle adapted to engage an open-ended engine block below the cylinder, and spring-urged expansion means cooperative with the crank shaft for holding the receptacle in engagement with the block.

In testimony whereof I have affixed my signature.
